          Abstract

          This report discusses a rare case of retroperitoneal infection caused by Trichosporon spp. in a 68-year-old immunocompetent woman following a nephrectomy. Trichosporon spp. was identified through meticulous mycological examination. This case challenges the typical association of Trichosporon infections with immunocompromised patients, emphasizing its potential pathogenicity in immunocompetent individuals. The importance of accurate identification, especially in postoperative infections and broad-spectrum antibiotic contexts, is highlighted, emphasizing the need for a thorough diagnostic approach in such cases.

          In vitro antifungal susceptibilities of Trichosporon species.

          The in vitro activities of amphotericin B, itraconazole, fluconazole, voriconazole, posaconazole, and ravuconazole against 39 isolates of Trichosporon spp. were determined by the NCCLS M27-A microdilution method. The azoles tested appeared to be more potent than amphotericin B. Low minimal fungicidal concentration/MIC ratios were observed for voriconazole, posaconazole, and ravuconazole, suggesting fungicidal activity.

            Trichosporon on humans: a practical account.

            Six human pathogenic Trichosporon species are described with respect to criteria for routine identification, epidemiology and clinical origin: T. ovoides, T. inkin, T. asahii, T. asteroides (Fissuricella filamenta), T. cutaneum, and T. mucoides. These species are causative agents of white piedra and cutaneous infections and are involved in systemic, localized or disseminated mycoses, particularly in patients with underlying haematological malignancy. Data on in vitro sensitivity to antifungal drugs are provided.

              A rare case of infective endocarditis complicated by Trichosporon asahii fungemia treated by surgery.

              The patient was a 58-year-old male. He consulted our hospital because of weight loss and fever. Computed tomography (CT) revealed renal infarction. Nine days after admission, CT showed hemorrhagic cerebral infarction in the right frontal lobe. A blood culture revealed streptococcus oralis, and echocardiography revealed vegetation in the mitral and aortic valves, suggesting infective endocarditis (IE). Fever (39 degrees C or higher) was noted 23 days after admission. A blood culture revealed Trichosporon asahii (T. asahii), suggesting T. asahii fungemia. An intravenous drip of fluconazole at 400 mg/day was initiated, and two-valve replacement was performed 34 days after admission. Following surgery, the patient became negative for beta-D glucan and was discharged 85 days after admission. We report the present case of IE complicated by T. asahii fungemia, which is rare in patients other than malignant blood disease or tumor patients, showing a poor prognosis in which survival was achieved by surgery.
